kimber is too fast for fast josephs.
the suggestion for MIT is right on.
you might also try AQ Midnight.
wire creek to mac with MIT-s as well.
your amp/passive pre- combination is near-perfect with high input sencitivity, low feedback and high input impedance of your poweramp.
also you might not have enough power to swing RM22 and I would suggest to get another same Mac(plenty on ebay to fight for) to use them as monos.
